I have an Elinox Lumberjack, bought sometime in the late 1970s. It went lost in a desk drawer (don't ask), but resurfaced not long ago. The Lumberjack, for those who don't know, has a main blade, a cap lifter/screwdriver, and a saw. That's all. Here's the SAK wiki on it:

Mine's the economy model. To the extent I can reconstruct my thinking in buying it, the following were factors: backpacking usage, cheap to buy, freeze-dry food so no cans to open, no weight taken up with tools I didn't think I'd need on the trail, and cheap, cheap, cheap.
The tool set looks a wee skimpy now, but it was adequate at the time, and that saw did get used. Confession: I have a walking stick, much used over the 35+ years since it was a
live black-birch sapling [oh, no!] I cut down with the saw. This was in a thicket of birches in a
Canadian provincial park [oh, no! oh, no!] on the north shore of Lake Superior.
Mea culpa.
These days, I'd just get a Farmer and be done with it — that's my recommendation to you.
And I'd probably cut that walking stick again today if I didn't already have it. It's been up Mt. Washington several times, down to the bottom of the Grand Canyon on a one-day rim-to-rim, and it helped me ford a quicksandy stream in Canyon de Chelly, to mention a few places it's been.
